Plant container

ABSTRACT

The invention is for a plant container consisting of decayable and ecologically safe materials. The plant container is collapsible and assembled from its parts consisting of a pre-cut casing ( 1 ) and a bottom ( 2 ) using known materials. The casing ( 1 ) and the bottom ( 2 ) are made of dimensionally stable wire mesh or biologically degradable plastic. The casing ( 1 ) and the bottom ( 2 ) are assembled with a decayable organic material which is attached to the dimensionally stable wire mesh or biologically degradable plastic.  
     The particular advantage is that the plant container can be inexpensively transported and easily assembled just before it is put to use.  
     It is permeable to water and air. In regions with high precipitation it prevents the accumulation of wetness and root rot and mildew. The formation of spiraling roots is hindered and a safe growth of the plant promoted. The plant container is robust and dimensionally stable and therefore suited for planting machines and devices as well as forklifts. The work in nurseries can be significantly rationalized.

[0001] The invention is a plant container made of decayable and ecologically safe materials such as is used in the cultivation of young plants.

[0002] The DE 82 12 729 U1 shows a plant container for the cultivation of seedlings which can be produced from the saturated bituminous paper and by means of folding or joining together the parts of the container cut from a band material. With this technical solution there is the disadvantage that such plant containers does not provide the stability required for the cultivation of larger seedlings and as a rule has to be removed prior to the transplanting. To the extent that they remain in the ground after planting, the bituminous paper makes it more difficult for the roots to grow through the casing and the bottom. In addition, bituminous paper is not ecologically safe.

[0003] A planting pot is known from DE 195 32 309 A1 that is formed from ring-shaped arched mats with overlapping zones in which the bottom is placed and which are made of a regenerative degradable organic fiber which is solidified with additives. According to this invention there is a support in the bottom made out of a ring-shaped mat ring casing of the planting pot in the inside bottom area. One or more bottoms may be placed on this ring and the overlappings of the ring casing are attached to this with backstitching.

[0004] While this planting pot has the advantage that it is made out of only degradable and insecticide-free material and is therefore ecologically safe, its use for cultivating larger seedlings is, however, limited, because the planting pot dos not show the necessary stability to resist the high pressure incurred by the transport of larger tree-like plants that have been cultivated for longer periods. In addition, the transport and storage of the planting pots shown is associated with significant costs.

[0005] The task of the invention is therefore to provide an improved plant container made of decayable and ecologically safe materials that is also suitable for the cultivation of larger, tee-like plants and that can be inexpensively stored and transported.

[0006] The task is solved by means of the invention with a plant container with the characteristics in claim 1. advantageous features of the invented plant container are to be found in the characteristics of the sub-claims 2 to 6.

[0007] The special advantage of the invention is that the plant container is collapsible and only needs to be set up on-site, immediately prior to use and that this can be done very easily.

[0008] This makes it possible to transport it inexpensively, for instance, on pallets, as well as an inexpensive storage of such plant containers. Furthermore, it is also suited for the cultivation of larger, tree-like plants. The weaving of wire or biologically degradable plastic makes it possible for the plant container to remain dimensionally stable for transportation even after longer periods of cultivation.

[0009] The invented plant container can also be planted with the plant in the soil after the plant has been cultivated.

[0010] The decayable material used and wire weave or biologically degradable plastic of the casing and bottom of the plant container guarantee the necessary stability and shape of the plant container for the cultivation period of the plant. It is permeable for both water and air. Even in regions with seasonally-based high volumes of precipitation, there will be no accumulated dampness and therefore no root rot or mildew.

[0011] The plant container also provides the advantage of undisturbed root penetration. It prevents the formation of spiraling roots and promotes a safe growth of the plant at the intended site.

[0012] the formation of spiraling roots has always been a special problem at nurseries. Such roots grow in circles along the wall of the plant container. Quite often plants at nurseries stand in planting pots for longer periods and thereby form a thick tangle of spiraled roots. If this tangle is not untangled when the plant is transplanted, the spiraling roots are disadvantageous to growth and the stability of the trees or larger bushes.

[0013] With the invented planter container the root system is able to develop in the ground without any disruption. Trees and larger bushes demonstrate a relatively good stability even after a short time and are resistant to the influence of the wind. It is not necessary to put holes in the walls of the plant container, as is currently state of the art with plant containers, to eliminate the formation of spiraling roots. The decay begins at the proper time with the invented plant container, when it is placed in the ground. The dimensional stability and stability of the invented plant container also makes it possible to transplant in the first 1 to 2 years if necessary.

[0014] When trees or larger bushes stand in a nursery for longer periods of time, the invented plant container also acts against the damaging effect of intensive sunshine and against the drying influence of wind a a result of its walls of decayable material.

[0015] In addition, plants in the invented plant containers that have longer standing times in nurseries can be transplanted to larger plant containers without any problem without having to remove the previous plants. Even more importantly the plants gain even more stability through the transplanting.

[0016] In the following the invented plant container should be explained in detail on the basis of drawings.

[0017]FIG. 1 The plant container in unfolded and connectible form,

[0018]FIG. 2 The cross-section of a stabilized casing of the plant container

[0019]FIG. 1 shows a plant container in the unfolded form with the casing 1 and the bottom 2 in a cross-section. The casing 1 and the bottom 2 of wire mesh or biologically degradable plastic are formed in this design from the rectangular elements 3; 4; 5; 6 and 7 of the wire mats, which are connected to one another in a flexible manner by means of the connecting elements 9.

[0020] In this unfolded form it is inexpensive to transport and store the plant container and easily assemble it together on site. With easily obtained materials such as hooks and s-shaped clamps the ends of the casing 1 are mechanically connected to one another and the bottom 2 attached to casing 1.

[0021] To assure the required solidity and stability of the plant container for the weight and the pressure to be borne, the diameter of the wire and the width of the mesh of the wire mat 8 will be dimensioned in accordance with the intended size of the plant container.

[0022] In the execution example shown in accordance with FIG. 2 the wire mat 8 is covered with coconut matting 10; 11 on both sides. As can be seen in this figure, the coconut mats 10; 11 are attached to the wire mat 8 by means of backstitching 12 out of decayable material, preferably jute or cotton. Instead of coconut mats 10; 11another decayable material may be used, such as excelsior, a mixture of cellulose and fabric or jute. The coconut mats 10; 11 may also be attached to the wire mat 8 with nails, glue or clamps.

[0023] To assure that the humidity, especially in the summer period, is held in the plant container during the cultivation period, it is possible to place a biofoil 13 or a fleece, a layer of paper stabilized with natural fiber or a fiber of decayable material between the wire mat 8 and one of the coconut mats 10; 11, in this case coconut mat 10 as shown in FIG. 2. the use of a fleece also has the advantage that in the pre-cultivation, the energy-rich main root of the plants can initially penetrate the fleece without difficulty and as a result of the restriction caused by the fleece many new roots can be formed that are important for the subsequent transplantation. The compact mesh of roots formed in this manner quickly provides the plant with the necessary hold after inserting the plant container in the ground, it aids in the uptake of nutrients and therefore reduces the loss by transplanting.

[0024] The casing 1 and the bottom 2 of the plant container are light and inexpensively produced. The elements 3; 4; 5 and 6, made of dimensionally stable weave or grid mat 8 made of wire or biologically degradable plastic are attached to a slightly pressed coconut mat 10 in the manufacturing process and then covered with a lightly pressed coconut mat 11.

[0025] By means of backstitching 12 along the length the mats 10; 11 are attached to the wire mat 8 and are then separated from the coconut web according to the dimensions of the casing 1. the separation can also be made in such a manner that a part of the coconut mat 10; 11 extends beyond the wire mat 8 so that the casing 1 can be joined by overlapping when the plant container is assembled on site. The coconut mat extending beyond the upper edge of the casing 1 can be folded inward and cover the wall of the casing.

[0026] The bottom 2 of the plant container is assembled in the same manner and can be shaped in a variety of ways. It can be circular, elliptical or multi-cornered. The casing 1 can be shaped to match the bottom 2. With a round bottom it is bent in a ring if the plant container is to be conical-shaped. In a multi-cornered bottom shape the casing will have a corresponding rectangular shape whereby the elements of the wire mat 8 of the casing 1 will be executed to match with the element of the wire mat in the bottom 2.

[0027] The invented plant container is characterized by its robustness and stability. It is therefore also suited for planting machines and devices and forklifts. It is therefore a very effective tool for conserving working processes, especially in nurseries.
